HOTflow® Forced Circulation Heater

HOTflow® forced circulation engine heaters feature an integrated pump that circulates warm coolant throughout the entire engine at uniform temperatures. Constant circulation of the coolant eliminates hotspots that can deteriorate heater hoses, harm engine seals and diminish coolant life. HOTflow® engine heaters rely on fewer heating cycles — saving up to 35% in energy consumption while extending heater element life and reducing maintenance work.

Markets served: Generator, Heavy Equipment, Truck & Bus, Marine, Railroad
